Hypertension affects approximately one-third of the US adults. This study investigated antihypertensive utilization patterns among hypertensive patients who were prescribed treatment, yet still experienced uncontrolled hypertension. Data from the Decision Resources Group Real World Evidence Data Repository US database (2015-2016) were used to construct a cohort of uncontrolled hypertension patients to observe antihypertensive utilization patterns. Results for 5059 patients, with an average age of 57.8 (SD = 13.7), who had, on average 2.4 agents prescribed. Approximately half (51.9%) were female, and most were White (86.8%). More than one-third (N = 1877; 37.1%) of patients were diagnosed with diabetes mellitus (DM) or chronic kidney disease (CKD) that could independently contribute to increased cardiovascular complications. Overall, the most common treatments prescribed, as percent of agents and as percent of patients, respectively, were diuretics (24.9%; 59.6%), followed by angiotensin-converting enzyme inhibitors (ACEIs) (23.8%; 56.9%), beta-blockers (BBs) (18.7%; 44.8%), calcium channel blockers (CCBs) (15.4%; 36.8%), and angiotensin II receptor blockers (ARBs) (13.5%; 32.3%). Approximately one-tenth (10.5%) of the prescriptions were written for fixed-dose combination therapies. Among patients diagnosed with DM and CKD (N = 200), the order of the most common agents was the same as the overall cohort. Only 5.6% of prescriptions written for these patients were fixed-dose combination therapy. Based on clinical guidelines, which suggest using ACEIs, ARBs, or CCBs as first-line therapy, and fixed-dose combination therapy to increase adherence, this indicates over-prescribing of BBs and under-prescribing of fixed-dose combination therapy. These findings illustrate the need to further investigate challenges faced by patients and providers in treatment decision-making.
